Doric Pilasters. The plan adopted by the Greeks in their Doric temple structures, was one that would necessarily increase the im portance of the column shafts, and required a sharp demarcation between the fluted columns and the contrasting plain wall surface. In the early temples with an entrance porch, the side walls were carried forward, and their ends were finished by a pilaster treatment on their front, returning on the two sides; while two columns were placed between them. These slightly projecting pilasters, termed antae, used by the Greeks, are employed for the most part upon the ends of walls. An elevation of the front of such a building (Plate XXXV), gives us the effect of an entrance porch composed of two columns and two pilasters, the latter supporting, on each side, the ends of the entablature overhead. In Greek architecture these pilasters are seldom used in important positions, on account of the extreme importance given to the column, and the resulting fact that the Greeks so arranged the plans of their buildings as very seldom to require the use of a pilaster in any important location. Of course, being placed behind a series of columns in this fashion would naturally render the pilaster very unobtrusive, and this effect was emphasized by its manner of treatment as a part of the wall itself. The shafts of these pilasters are always plain, and never given any entasis, being the same width at the top as at the bottom. The capitals differ very radically from the capitals of the column, inasmuch as they consist of merely a series of fine mouldings below the abacus and set on top of one or more fascias, as in Fig. 91. The contrast offered by the plain surface of these pilasters to the fluted columns with which they are ordinarily used, is very effective, while by their very character, when seen from any distance, they tend to become a part of the wall to which they were attached.
